aðalslega

Aðalslega is an Icelandic adverb meaning primarily, chiefly, or in essence. It is a relatively rare variant of the more common adverb aðallega and is mainly found in older or dialectal Icelandic. In contemporary standard Icelandic, aðallega is the preferred form.

Etymology and form: The word is derived from the adjective aðal (“main, principal”) combined with the adverbial suffix -lega, yielding a meaning close to “in a main way.” The spelling with an inserted -s- is considered a historical or dialectal variation, and modern usage tends to favor aðallega.

Usage and register: Aðalslega serves to mark the principal aspect of a statement, equivalent to “primarily” or “mainly.” Because it is uncommon in modern writing, its occurrence can sound archaic, formal, or regional. For most purposes, aðallega is recommended, while aðalslega may be encountered in texts aiming to reflect older style or local speech.

Variations and related terms: Related terms include aðallega (the standard form) and megin (in the sense of primarily or mainly). The two forms are not interchangeable in all contexts due to stylistic and historical usage differences.
